Dubai Telegraph - Stocks volatile after soft US growth data, court ruling against tariffs

But the uncertain outlook for the world's biggest economy and the risk of US military strikes against Iran over its nuclear programme kept investors cautious heading into the weekend.

Crude prices pulled back as traders weighed the chances of US action that could threaten Middle East oil supplies.

In the United States, the economy grew 1.4 percent in the fourth quarter, well below the 2.5 percent analysts had forecast, while a price index for December rose to 2.9 percent, more than anticipated.

That poured cold water on hopes that US growth was holding up and inflation was contained despite Trump's tariffs barrage, and complicated the outlook for more interest rate cuts by the Federal Reserve.

The data came after weeks of Wall Street losses on fears that massive AI investments may be overdone, and that the technology will undermine swathes of traditional business models.

"Today's reports are unlikely to lift markets out of their current environment," said Bret Kenwell, US investment analyst at eToro.

In Europe, a closely watched survey on Friday showed that business activity in the eurozone accelerated in February, indicating that the region's economy is on more stable footing.

British firms also boosted output in February, according to the purchasing managers' index published by S&P Global.

Stock indices were higher across most of Europe, while in Asia, Hong Kong fell as it reopened from a three-day break for the Lunar New Year, and Tokyo was also down.

Oil prices slipped after climbing to six-month highs this week on worries that nuclear talks between the United States and oil-rich Iran might not avert a conflict that could threaten supplies.

Trump warned Thursday that Tehran should make a "meaningful deal" in negotiations with Washington in the next 10 days or else "bad things happen".

"At its core, this looks like pressure and leverage rather than a prelude to invasion," said City Index market analyst Matt Simpson.
